Don't know if you solved your problem yet, but i suggest you find some Ryzen 2000 to update the BIOS to last version P3.20 and then try again with your 3900x.]]> Sun, 05 Jan 2020 22:14:05 +0000 https://forum.asrock.com/forum_posts.asp?TID=13226&PID=71786&title=x470d4u22t-wont-post#71786 https://forum.asrock.com/forum_posts.asp?TID=13226&PID=71365&title=x470d4u22t-wont-post#71365 Author: Doug-W

I reached out to support but am also reaching out here to see if anyone has seen this:

I'm having problem with my new X470D4U2-2T. Depending on whether I'm clearing the cmos or not i'm getting a 61 or a b6 in Dr. Debug. Per https://www.asrock.com/support/faq.asp?id=334
I see 61 is a chipset initialization and b6 is not documented.

I'm running a Ryzen 9 3900X and I'm not sure what the BIOS is since it will not POST. https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U2-2T#CPU indicates that 3900x is only supported since P3.10

I've tried two sets of memory from the QVL List at https://www.asrockrack.com/general/productdetail.asp?Model=X470D4U2-2T#Memory first 128GB of Samsung M391A4G43MB1-CTDQ
then suspecting a bios issue, 16 GB of Crucial CT16G4DFD8266.C16FD1. Both are acting the same way.

I'm also unable to IPMI in at the part where the POST is failing perhaps because that is not initialized until later.

Is this a defective board? What are my next steps?
